I've a good memory. I tend to live in a cluttered place because it's easier to remember where I left stuff than it is to tidy and re-remember. I remember almost every reference book I read. I don't re-read novels.

For me, it's just that I've never seen the point. All the people I know who have been the most annoying as far as "accidentally" or "unknowingly" forwarding viruses, or mass-mailing stupid shit, have been people who have extensive address books. And people who are most hurt when things break are people who have extensive address books.

By relying on my memory, I don't get lulled into thinking that my email contacts will always bee available to me. And if something does happen-- my account gets hacked or whatever-- I don't have to apologize to my friends.

Why not? Most people's email addresses are fairly simple to relate to who they are as a person. My sister's, for instance, is her name. For others, it's a regular internet handle that I already had to memorize for chat.

And, for people who I email regularly, it's habit.

If I need to remember an address of someone who has already emailed me, and I can't remember their email address, I can search for their name to pull up the last-known-address.
